一、前言 永磁磁滞马达是一种具有高的启动力矩的同步马达,它的显著优点是利用转子材料本身的磁滞性能自行启动;而不需要其它辅助启动装置,用作永磁磁滞马达的转子材料较多的采用价格昂贵的Fe—Co—V合金棒材,由于加工性能较差,加上转子内孔加工造成材料浪费较大,采用Fe—Co—Mo合金管材后,制作转子工艺简单,成形后只需切割即成,成材率高,性能稳定,在生产上有较 I. Introduction Permanent magnet hysteresis motor is a high starting torque synchronous motor, its significant advantage is the use of the rotor material itself hysteresis performance of self-starting; without the need for other auxiliary starter, as the permanent magnet hysteresis Rotor material of the motor is more expensive Fe-Co-V alloy bar, due to poor processing performance, coupled with rotor bore material processing caused by a larger waste, the use of Fe-Co-Mo alloy pipe, the rotor The process is simple, just cut after forming, finished product rate, stable performance, in the production of more
